More than 3,000 counties and the District of Columbia can compare how healthy their residents are and how long they live with the 2012 County Health Rankings. The Rankings are an annual check-up that highlights the healthiest and least healthy counties in every state, as well as those factors that influence health, outside of the doctor’s office. The Rankings highlight the importance of critical factors such as education rates, income levels, and access to healthy foods, as well as access to medical care, in influencing how long and how well people live.
